Shocking medical scans

This undated photo of an X-ray, released by Utah Valley Regional Medical Center, shows all the hardware, plates and screws that were required to fix a fracture ankle caused in a jump gym. You'll see a lot of these very severe, open wounds that you don't see unless you're in a high-velocity type of injury," Dr. Craig Cook, trauma director at Utah Valley Regional Medical Center said. "This is like a war type of injury or a motor vehicle crash."

A 20-month-old girl named Olivia Smith accidentally impaled herself on a pencil. The writing tool entered through her right eye socket and lodged itself into the left hemisphere of her brain. Luckily, it missed all major arteries, veins and nerves, so doctor's were able to remove it without any permanent damage.

Mexican doctors successfully removed a 33 pound tumor from the toddler that was heavier than his body weight.

Grenade lodged in jaw

In September, 2011, Mexican street vendor Karla Flores checked into the emergency room in her home state of Sinaloa with a grenade lodged in her face. She appeared to have been caught in the crossfire when someone shot off a rocket-propelled grenade. Doctors and bomb experts weren't sure, but the bomb most likely didn't go off because the pin was being held shut by her jaw. Using only local anesthesia, the unprotected medical team wheeled Flores to an empty field and gave her a tracheotomy so she could breath. They and a bomb-disposal team removed the grenade without it going off.

They say a picture is worth a thousand words, but some of the images on this list might leave you speechless.

Medical imaging scans like an X-ray, CT scan or ultrasound can tell doctors what's wrong with a patient, and in the case of many of these scans, doctors were given a clear picture of odd objects patients ingested or were impaled by. With X-rays generously provided by Dr. Tim B. Hunter, professor of radiology at the University of Arizona, and others pulled from the headlines, here are 21 shocking X-rays and imaging scans.

Pictured here is a person who appeared to shove a pen into his head.

Running with sharp objects

This scary-looking image shows what can happen when a toddler runs with a pen in his mouth. When he fell, the pen went through the inside of his upper lip - and kept going until it had reached almost to the eye socket. But he was lucky - it came out and he was fine.

Blowgun

To a boy, playing with a blowgun sounds like great fun. Only this boy sucked when he should have blown - and inhaled a corsage pin into his windpipe. Luckily, doctors were able to retrieve it without too much trouble - and the boy went home none the worse.

Antenna accident

Mom was hysterical when her young son came home with a car's radio antenna protruding from his chest. Seems he had been playing in a tree when he fell, landed on a junk heap, and an antenna impaled his rectum, going clean through his body and out his chest. Amazingly, no major organs were injured. Once doctors removed the antenna, the boy made a full recovery.

Not-so-routine mammogram

This bullet, lodged in a woman's left breast, was discovered during a routine mammogram years after she had been shot. It didn't seem to pose any threat to her health, so doctors left it in place. She told doctors that the man who shot her was dead.

Heroin smuggle gone awry

Some drug "mules" swallow drug-filled condoms or balloons before passing through customs, intending to collect the drugs once they've been passed. But it's risky business. If even one of the condoms ruptures while still inside the body, the result can be a gigantic overdose - possibly fatal.

Some nuts aren't for eating

This is what happened when a poorly supervised mental patient got hold of some nuts - the kind that screw onto bolts. At the point the x-ray was taken, the nuts were partway through the small intestine. They eventually passed without incident.

Swallowed Buckyballs

Swallowed razor blade

The abdomen in this x-ray belonged to a mentally unstable man who swallowed a box-cutter blade. "Swallowing objects is very common in mental institutions," says Dr. Tim B. Hunter, professor of radiology at the University of Arizona and a collector of unusual X-ray images. But the blade passed without harm. Once they reach the large intestine, says Dr. Hunter, swallowed foreign bodies often pass without harm.

Foot pain

This is what can happen when you step on a pen. Doctors frequently x-ray such injuries to make sure there is no damage to the bone. The soft tissue heals quickly with minimal treatment.
